Motto/theme: Query caching through quality-of-service concept

The 1.3 series aims to improve the performance of applications
and the overall load of an asynchronous MySQL cluster, for
example, a MySQL cluster using MySQL Replication. This is done
by transparently replacing a slave access with a local cache
access, if the application allows it by setting an appropriate
quality of service flag. When using MySQL replication a slave
can serve stale data. An application using MySQL replication
must continue to work correctly with stale data. Given that the
application is know to work correctly with stale data, the slave
access can transparently be replace with a local cache access.

PECL/mysqlnd_qc
serves as a cache backend. PECL/mysqlnd_qc supports use of
various storage locations, among others main memory,
APC and MEMCACHE.
